Training and Qualifications of Qualified Workers

DOE-HDBK-1092-2004

and by functioning to de-energize the circuit when an arc fault is detected (NEC 210.12 and

550.25). AFCIs are evaluated to UL1699, Safety Standard for Arc-Fault Circuit Interrupters,

using testing methods that create or simulate arcing conditions to determine the product's ability

to detect and interrupt arcing faults.

Although NEC 210.12 requires that AFCI protection be provided on branch circuits that supply

outlets (receptacle, lighting, etc.) in dwelling unit bedrooms, there is no prohibition against

providing AFCI protection on other circuits or location other than the bedrooms. For example,

aircraft wire systems utilize AFCIs for newer installation to trip the circuit routed through

sensitive areas such as fuel storage areas.

TRAINING AND QUALIFICATIONS OF QUALIFIED WORKERS

Only qualified workers shall perform work on electrical systems. It is dangerous for unqualified

personnel to attempt to do electrical work. There should be an employee training program

implemented to qualify workers in the safety-related work practices that pertain to their

respective job assignments.

2.8.1

FORMAL TRAINING AND QUALIFICATIONS

Management should establish formal training and qualifications for qualified workers before they

are permitted to perform electrical work. Refresher training is recommended at intervals not to

exceed three years to provide an update on new regulations and electrical safety criteria.

The training shall be on-the-job and/or classroom type. The degree of training provided shall be

determined by the risk to the employee. This training shall be documented. Qualified

employees shall be trained and familiar with, but not be limited to, the following:

1. Safety-related work practices, including proper selection and use of PPE, that pertain to

their respective job assignments.

2. Skills and techniques necessary to distinguish exposed live parts from other parts of

electrical equipment.

3. Skills and techniques necessary to determine the nominal voltage of exposed live parts,

clearance distances, and the corresponding voltages to which the qualified person will be

exposed.

4. Procedures on how to perform their jobs safely and properly.

5. How to lockout/tagout energized electrical circuits and equipment safely.

Other types of training recommended for electrical workers include the following:

a. National Electrical Code (NFPA 70) (2002)

b. National Electrical Safety Code (ANSI C2) (2002)

c. Use of personal protective grounds

d. Use of testing and measuring equipment
